Ethane enters furnace at 0.9 kg/min and burns with 200% excess air. 50% of fuel is consumed and combustion is assumed complete (meaning no CO is produced). Find the flow rate of Oxygen, Nitrogen, and Air at the inlet, the molar flow rate of all species, and the mass flow rate of water vapor in the exit stream.
A 20.0 mL sample of 0.150M KOH is titrated with 0.125M HClO4 solution. Calculate the pH after the following volumes of acid have been added.
It is produced natrually from degradation of organic matter, and also anthropogenically from fuel combustion.) The acid dissociation constant, Ka for formic acid is 10-3.7. Assume T=4*C and I=0.
Calculate [OH-] and pH in a solution in which dihyroden phosphate ion, H2PO4-, is 0.355M and hydrogen phosphate ion, HPO4 2- is
methyl salicytate is heated in water, salicylic acid and methyl alcohol form. HOC6H4COOCH3 + H2O --> HOC6H4COOH + CH3OH 4.0mL Methyl Salicitate
Determine the Ka value of acetic acid at 105 degrees C from the following data: A 0.3 Molar aqueous solution of acetic acid shows a pH of 2.642 at 105 degrees C. You can use the approximation formula here because the concentration of the acetic ac..
Compound X is a miracle drug used to cure every sneeze and sniffle. It is very expensive though and customers complain it doesn't always work as well as it should.
Give the reaction products of sodium borohydride (followed by acidification) with the following compounds. a) acetone
The radius of the Earth is approximately 6370 km. if one could dig down straight towards the center of the Earth, one would find that the innermost 3480 km (the core) has an average density of about 11.g/cm^3.
Explain why acid chlorides can be used to prepare amides but amides are not generally used to prepare acid chlorides?
b. Would the pH increases or decreases if the solution is disturbed by adding HBr?
Calculate the change in molar enthalpy and molar internal energy when carbon dioxide is heated from 15 degrees Celsius to 37 degrees Celsius
